Three RCTs showed that rubber band ligation was better than injection sclerotherapy in a variety of outcomes (pain, repeat treatment, prolapse, bleeding) in persons with mainly second-degree hemorrhoids; however, rubber band ligation was associated with more immediate adverse effects.
Edema is the medical term for swelling. Body parts swell from injury or inflammation. It can affect a small area or the entire body. Medications, infections, pregnancy, and many other medical problems can cause edema. Edema happens when your small blood vessels become leaky and release fluid into nearby tissues.
Edema is swelling caused by the abnormal buildup of fluid in the body. The fluid collects under the skin within the tissues that are outside of the circulatory system. The circulatory system carries blood through the body. Edema is most common in the feet and legs.
